Reads in all data from a Microwave Telemetry Inc. fish report and parses all pieces into a list. Currently, the only information not readin is the light based locations while the PSAT tag is floating at the surface. This function uses the RODBC library and several sub functions to connect to an excel file and read in the contents. This does not work for Linux users. If ODBC=F, the gdata
package is used to extract information. While this is appreciably slower to implement, it it now cross platform.

|
tagID |
PTT number or other unique identifier of the tag to be read in. Must be of class 'character' |
tyear |
Year the fish was tagged. Must be of class 'numeric' |
xlsfile |
Fish report from MTI containing all your valuable data. |
taglocfile |
A text file containing tagging date and location in the following columns: Id, Year, Month, Day, Longitude (-180 to 180), Latitude. Do not use a header. |
delta |
Flag to remove delta limited values in Depth and temperature |
minmax |
Flag to import minimum and maximum temperatures from newer MTI fish reports |
odbc |
If working on a windows system, flag to use ODBC connectivity. If on Linux, leave this False. |
A list with the following:
x0 |
Tagging Location |
day0 |
Tagging date of Class 'date' |
day0b |
Tagging date of Class 'POSIXct' |
xT |
pop-off location |
dayT |
pop-off Date of Class 'date' |
dayTb |
pop-off Date of Class 'POSIXct' |
fulldates |
Alldates fish was at liberty of Class 'date'. This does not neccesarily correspond to how many days of data are returned |
SRSS |
Data frame of Sunrise and Sunset times. Columns are: Date, Sunrise and Sunset with SR and SS in minutes past midnight. Date is of Class'date' |
MWTxy |
Data Frame of Microwave Telemetry produced light based geolocations and corresponding dates. Columns are: Year, Month, Day,Latitude and Longitude (-180 to 180) |
T |
Matrix of ambient temperatures. Columns correspond to time of day GMT (typically 0-23.75 hours) and Rows corrspond to days at liberty. This matrix contains both observations and any times missing observations |
Z |
Matrix of depth. Columns correspond to time of day GMT (typically 0-23.75 hours) and Rows corrspond to days at liberty. This matrix contains both observations and any times missing observations |
Argos |
Data Frame of Argos data returned while tag was floating. Columns are: Date-Time (character class), Argos Location Class, Latitude and Longitude. |
